KSM02.1B-076C-35N-M1-HG2-ET-SD-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-076C-35N-M1-HG2-ET-SD-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By combining an AC synchronous motor with embedded inverter electronics and network connectivity, it provides decentralized motion control directly on the machine frame. The assembly regulates position, speed, and torque in automated packaging, assembly, and material-handling equipment without requiring a separate cabinet-mounted amplifier, which reduces wiring and conserves control-cabinet space.

Power enters the unit through a hybrid connector that carries the DC bus, control power, and communication lines in one sealed coupling. Thermal energy dissipates through natural convection, so no fans or liquid-cooling circuits are required when free airflow surrounds the housing. Real-time setpoints and diagnostic data travel over Multi-Ethernet, allowing the system to use protocols such as PROFINET, EtherNet/IP, or EtherCAT after setup. Rotor feedback is handled through a Hiperface interface, which supports the automatic transfer of motor parameter data to the controller. The integrated power stage operates from a DC 750 V supply rail, allowing the drive to share a common DC link with other axes on the same machine.

Position feedback has a resolution of 128 signal periods per revolution, while a battery-free multi-turn absolute counter preserves the turn count when the main power supply is disconnected. Load retention is provided by an electrically released holding brake that engages when its coil is de-energized. The brake coil receives power from a dedicated DC 24 V service source distributed through the single-cable interface. The motor uses a C-length stator, frame size 076, and winding code 35 to provide continuous torque for demanding motion cycles. A plain shaft transfers mechanical output, while an integral shaft seal helps protect the internal components from moisture and contaminants. The integrated Safe Motion function with Safe Brake Control supports controlled braking in operator-accessible machinery and coordinates brake operation with the drive's safety system.
